United States Patent TOILET SEAT LOCK Adolph J. Bruckner, Fargo, N. Dak.

Application July 24, 1951, Serial No. 238,347

2 Claims. (Cl. 4-253) The present invention relates to a toilet seat lock and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a lock for toilet seats which may be quickly and easily attached to the conventional hinge on one side of the seat. There is provided an up wardly extending arm in which is revolubly mounted the shaft of a handle. A dog extends rearwardly from the upper end of the arm and a spring is interposed between the forward side of the arm upon the shaft and a nut which is threadably mounted upon the outer end of the shaft to adjust the tension of the spring. The device prevents the seat and cover from being lifted by children so that they will be prevented from playing in the toilet water or throwing things into the toilet which will plug the same. When a person desires to use the toilet he may unlock the device by utilizing the handle in a manner hereinafter set forth.

It is accordingly an object of the invention to provide a novel lock for toilet seats.

Another object of the invention is the provision of a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and eflicient in use.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is a side elevation of a toilet bowl and the toilet seat lock.

Figure 2 is a front elevation of the toilet seat lock attached to a toilet bowl.

In the drawing there is shown hinge post 20 with hinge post nut 21, and a rirne extension 22 of a bowl 23, provided with seat 24 and lid 25.

Referring more particularly to the drawing, there is shown therein a toilet seat lock comprising a base which is bifurcated at one end, as indicated at 11 and which has integrally formed therewith an upstanding arm 12.

Revolubly mounted in the upper portion of the arm 12 is a shaft 13 which is exteriorly threaded at its free end, as indicated at 14 and upon which is threadably mounted a nut 15. The other end of the shaft 13 has integrally formed therewith an operating handle 16 and a flange 19 and the upper end of the arm 12 has an outwardly extending dog 17 normally engaging the flange 19.

A compression spring 18 is interposed between the nut and the arm 12 and surrounds the shaft 13.

2,698,439 Patented Jan. 4, 1955 In operation, it will be apparent that the bifurcated end 11 of the base 10 may be inserted beneath the conventional hinge bolt of the conventional toilet seat by loosening the same and inserting the bifurcated portion therein and thereafter tightening the same. The type of toilet seat and bolt are of a type as shown by the patent to Schmitz, No. 2,578,153, December 11, 1951, see Fig. 6 thereof.

The spring bearing against the nut 15 and the arm 12 tends to move the shaft 13 to the left, as shown in the figure, to cause the periphery of flange 19 to normally engage the underside of the dog 17 frictionally to prevent easy rotation of shaft 13, and hold the handle 16 in various desired positions. When it is desired to prevent raising of the toilet seat cover by persons who do not understand the operation of the locking device, the shaft 13 is pulled by the handle 16 to the right against the force of the spring to free the flange 19 from engagement with the dog 17. The handle 16 is then moved downwardly so that its free end engages the cover of a toilet seat, when the handle is released. The spring 18 then causes the shaft 13 to be moved to the left to cause flange 19 to engage the dog 17 to hold the handle in the down position. To release the cover, the handle 16 is moved to the right to disengage the flange 19 and dog 17. The handle is then raised to a substantially vertical position and released when it will be held in such a position by the action of the spring, flange and dog 17. To again lock the device it is only necessary to move the handle 16 downwardly to the position shown in the drawing.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made Without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

1. In combination with a toilet bowl having attached thereto bolts associated with hinges for a toilet seat and cover, a device to prevent raising of the cover, comprising a horizontal base having a bifurcated end adapted to encompass a bolt, an upstanding arm at the other end of the base, a shaft revolvably mounted in the upper end of said arm, a nut threadedly engaging one end of the shaft, a compression spring positioned between the nut and arm, a handle connected to the shaft and at the angle thereto, and means on the shaft and arm to resist rotation of the shaft.

2. The structure set forth in claim 1 further characterized by means for resisting rotation of the shaft comprising a lug projecting from the arm and a flange on the shaft arranged to frictionally engage said lug.
